Ecosystem services of agricultural

Seminatural habitats regarding agricultural landscape
• Assessment of non-forest woody vegetation for
landscape planning
• Despite small size of seminatural habitats of
agricultural landscape , these patches often act as
refuges for biodiversity and may provide a wide range
of ecosystem services (ES) to populations and human
society.

Biodiversity research of historic structure of
agricultural landscape in Slovakia
project supported by the EEA Financial Mechanism, Norwegian Financial Mechanism
and state budget of the Slovak Republic, 2009 – 2011
Project objectives:
1. Complex inventory and typology of historic structures of
agricultural landscapes (HSAL) in relation to their biodiversity
2. Detailed, interdisciplinary research (investigation of biodiversity
in relation to ecological and socio-economical conditions of the
site) in 3 pilot areas.
3. The elaboration of a „Strategy for protection and management
of valuable biotopes of HSAL“ in pilot areas with respect to
principles of sustainable development
Interdisciplinary research of biodiversity
in 3 pilot areas
Man-conditioned habitats of the agricultural landscape - special
attention was given to vegetation connected to the forms of
anthropogenic relief
Relationships between natural conditions, land use, and culture
(natural and socio-economical limits at present and in the past)
Analyses of biotic, abiotic conditions, land use, socio-economic
conditions, demographic and sociological conditions on cadastral
level
Interdisciplinary research of biodiversity
in 3 pilot areas

Ecosystem services
The assessment was oriented to:
• Habitat services – biodiversity evaluation of favourable conservation
status of a natural and seminatural habitat and species, identification of
driving forces, and threats to the biodiversity of HSAL.
• Cultural-historical services – based on presence of typical features of
HSAL: preserved small scale structure of plot division, primary land use was
not changed during collectivization of agriculture, original forms of
anthropogenic relief and/or features of traditional agricultural technologies
have been preserved
Project results
•
Pilot areas – preserved original agricultural landscapes, which did not lose
shape and contour of the cultural–historical countryside (areas are less
accessible and remote, having marginal areas with extreme conditions of
nature).
•
Traditional agricultural historic structures often create specific living
conditions for biota, which have been documented by high species richness and
occurrences of many rare and threatened species (e.g. 327 spiders, 45
threatened and 2 new sp.); Species richness is dependent upon complex factors
and corresponds with: Abiotic factors; Type habitat; Orientation; Method of
cultivation
•
Results shows high significance of these habitats as islands of species-rich
habitats, they provide also many other environmental services.
Significance and ecosystem services of historic
structures of agricultural landscapes
(National grant agency VEGA project – 2011 -2014)
Particular objectives:
•
•
to get new knowledge on goods and ecosystems services provided by
ecosystem in HSAL
to study and quantify ecosystem goods and services on the examples of
pilot areas - to compare significance of HSAL with other agricultural
landscapes, which were reclaimed and don’t have features of HSAL
Significance and ecosystem services of historic
structures of agricultural landscapes
•
Development of methodological concept: selection and proposal of suitable indicators
for quantitative and qualitative assessment of ecosystem goods and services
provided by historic structures of agricultural landscapes.
•
Habitat services: maintenance of genetic diversity, maintenance of life cycles of
migratory species
•
Regulating services: GIS tools and special program for modelling will be used for
assessment of water and soil regulation, visualization of landscape view, etc.
•
Cultural ecosystem services – indicators for recreation and ecotourism, aesthetic,
inspirational, educational, sense of place, cultural heritage.
•
Provisioning services (food, water – irrigation, cooling, raw material, medical
resources, ornamental resources – have not decided yet)
•
Sociological survey will be oriented on perception of HSAL by land owners and users,
as well as visitors of the area.
Socio-ecological study of landscape and biodiversity changes in
mountain area of the Poloniny NP in context of global changes
National grant agency VEGA project – 2011 -2014
Project leader: Peter Bezák
Regional scale – Poloniny National park, NE Slovakia, ca 300 km2
Study area is dominated by forests - grasslands are the second
largest ecosystem, building a water reservoir and resettlement of this
area
Socio-ecological study of landscape and biodiversity changes in
mountain area of the Poloniny NP in context of global changes
• Semi-natural grasslands in main focus
• Assessment ecosystem services provided by grasslands and
proposal of suitable management for maintenance of ecosystem
services
• Changes in provision of ecosystem services after CAP start in
Slovakia – comparison of scenarios
Socio-ecological study of landscape and biodiversity changes in
mountain area of the Poloniny NP in context of global changes
Main aim of the project:
to develop causal chains of human-nature processes in the target region
• Detailed study of socio-ecological interactions, in the area, including
ecosystem services provision,
• Proposal of causal chains of human-nature processes in the landscape
• Identification of suitable future management of the region that will
maintain the multi-functionality and ecosystem services provision.
• Synthesis of biological research in the target region
